Using LNMP architecture to build Discuz instance

LNMP represents the web server architecture of Nginx+MySQL+PHP under the Linux system.

Linux is the general name of a kind of Unix computer operating system, and it is the most popular free operating system. Representative versions are: debian, centos, ubuntu, fedora, gentoo and so on.

Nginx is a high-performance HTTP and reverse proxy server, as well as an IMAP/POP3/SMTP proxy server.

Mysql is a small relational database management system.

PHP is a scripting language that embeds HTML documents executed on the server side.

These four kinds of software are all free and open source software, which are combined into a free, efficient and scalable website service system.

The general steps of this experiment are as follows:

​ install nginx → install mysql database → install php tools → set up Discuz forum

Install the nginx service

The software packages needed for this experiment will be remotely mounted in advance.

Let nginx support PHP function

[root@localhost etc] # vim / usr/local/nginx/conf/nginx.conf # # configure the nginx configuration file to uncomment the following location ~\ .php$ {root html; fastcgi_pass 127.0.0.1 usr/local/nginx/conf/nginx.conf 9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME / usr/local/nginx/html$fastcgi_script_name # # site path include fastcgi_params;} [root@localhost etc] # vim / usr/local/nginx/html/index.php # # Test php pages to add the following content

Establish bbs database

[root@localhost etc] # mysql-u root-pEnter password: # # enter the database with the password of abc23mysql > CREATE DATABASE BBS; # # create bbs database Query OK, 1 row affected (0.00 sec) mysql > GRANT all ON bbs.* TO 'zhy'@'%' IDENTIFIED BY' zhy94666' # # upgrade database user bbsuser as administrator and set password Query OK, 0 rows affected, 1 warning (0.00 sec) mysql > GRANT all ON bbs.* TO 'zhy'@'localhost' IDENTIFIED BY' zhy94666';Query OK, 0 rows affected, 1 warning (0.00 sec) mysql > flush privileges # # Refresh database Query OK, 0 rows affected (0.00 sec) mysql > quit # # exit [root@localhost etc] # systemctl restart nginx.service # # restart service 4. Install Discuz forum
